[Tutor] Object Destruction

[Gregg T. Geiger]

What are scope rules for class objects and when are they
destroyed, specifically with regards to for loops?

That is, if a class Spam is defined somewhere and used in a
for loop as follows:

for i in [0, 1, 2, 3, 4]:
  spam = Spam()
  # end of for loop

will an object be created and destroyed with each pass
through the loop or does each instance remain "alive"?  In
a comparable C++ loop

for (int i = 0; i < 5; ++i){
  Spam spam;
}

the destructor is called 5 times.  In my own experience
with Python, files opened in Spam are not closed each time
through the loop unless explicitly closed within the class.

Any insight(s) would be appreciated.

Thanks.

Gregg
